HYDRAULIC REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 425,541, dated April 15, 1890.

Application led June 29, 1888. Serial No. 278,562. (No model.)

which our invention appertains to make and use the same, reference being had to the accompanying' drawings, in which- Figure 1 is a perspective view of our iml proved refrigerator with the door open, ex-

posing its interior. Fig. 2 is a sectional side elevation of the device, showing more clearly a Water-compartment between the inner and outer casing. Fig. 3 is 'a vertical section through ma: of Fig. 2, and shows the pipes which serve to support the food opening into the water-chamber.

Similar letters of reference denote correspending parts in the several figures.

The object of our invention is to simplify the construction and improve the efficiency of that class of refrigerators in which water is used instead of ice as the cooling' medium for the preservation of the contents of said refrigerator.

Our invention consists in certain peculiarities in the construction, arrangement, and combination of the various parts, substantially as will be hereinafter described, andv then more particularly pointed out in the claim at the end of the specification.

Referring to the drawings, A designates the outer inclosingoase, which may be made of any size and, of any suitable material, and which is mounted upon the supporting-feet a, and is provided with a door C for giving access to the interior of the refrigerator. This case A is perforated at its top and bottom for the reception of the ends of pipes D and D', one of which pipes, as D, may be connected with any suitable water-supply, and the other, as D', forms an outlet for the water, lNithin this outer inclosing case A is situated a smaller case B, which contains the meats, vegetables, ra., to be kept cool. It will be observed that the front of this inner case B abuts against the front of the case A, and that it is made of such size that a space will be left upon three sides and above and below, forming a compartment A between the inner and outer case for the water.

The interior of the inner case B may be provided with a series of pipes E, extending transversely through the said case and projecting a slight distance out on each side into the water-compartment A. Obviously these pipes may forni supports for the meats, dac., to be kept cool, and the circulation of the water through said pipes will facilitate the preservation of the meats, the.; but we may dispense with these pipes, if we so desire, and place the meats, dac., upon trays, as in the ordinary refrigerator.

From the foregoing it will be obvious that in order to keep the contents of the inner case cool we iill the water-compartment A with water, the said water entering through the pipe D, and which by surrounding the inner case and circulating through the pipes E (when they are used) will keep the contents of the said inner case at all times cool and wholesome without the necessity7 of using ice.

It will be observed,further, that we may have a continual circulation of water through the compartment A', or we may, if We so desire, let the Water in until the water-compartment is filled and keep it there a certain length of time and then let it out through the pipe D' and refill the said compartment A" with fresh water.

We do not wish to be understood as'limiting ouselves to the precise construction herein set forth, as many of t-he details might be varied at will without departing from the general spirit of our invention and without in any way interfering with its usefulness.

Having now described the construction, objects, and advantages of our invention, and having set forth a preferred means of carrying the same into effect, what We believe to be new and desire to secure by Letters Patent, and what we therefore claim, is-

In a refrigerator, an outer casing having a door in one of its sides and also having an inlet and an outlet pipe, in combination Witha said food-receptacle and opening into said 1o foodreceptacle located Within said outer` Water-space at opposite sides of saidreoeptacle. casing, the said casing having an open end In testimony whereof We aix oursignatures abutting against the side of the outer easing l in the presence of two Witnesses.

5 at the point of location of the said door, where- JOHN J. GERAGHTY.

by said door will close both the outer casing FRANK J. GERAGHTY. and the food-receptacle, the said food-reoep- Witnesses: tacle also having a Water-space over five of J. V. CARROLL,

its sides, and Water-pipes extending through W. J. GERAGHTY.
